Filed: 1994-03-15
Abstract: PURPOSE: To surely inspect the functionality of a random probe accompanied by dynamic change by determining a reference value from the length of a switching period for changing a probe signal from rich state value to lean state value or from lean state value to rich state value under the operating condition of a random probe control circuit. CONSTITUTION: A switching period of the range for rapidly changing the signal from a random probe from a high voltage value showing air-fuel mixture rich state to a low voltage value showing air-fuel mixture lean state is measured. The reverse switching period from a lean state value of air-fuel mixture to a rich state value is also measured. The lengths of these switching periods show the scale quantity to the functionality of the random probe. When the switching period is situated above the limit value determined by use of the precise random probe before inspecting state, or corresponds to this limit value, the random probe is defected.
